Abstract

A Hall magnetic sensor working in the current domain and its electronic interface are presented. The paper describes the physical sensor design and implementation in a standard CMOS technology, the transistor level design of its high sensitive front-end together with the sensor experimental characterization. The current-mode Hall sensor and the analog readout circuit have been fabricated using a 0.18-μm CMOS technology. The sensor uses the current spinning technique to compensate for the offset and provides a differential current as an output signal. The measured sensor power consumption and residual offset are 120 μW and 50 μT, respectively.
